Cannot install Exchange 2010 on Win Server 2k8R2

Question

I am working in a Hyper-V lab trying to install Exchange 2010 on a Windows Server 2008 R2 server. When the installer gets to the Readiness Checks it keeps failing on the Client Access Role prerequisites, and Mailbox Role prerequisites with the following 2 errors: Unable to read data from the Metabase. Ensure that Microsoft Internet Information Services is installed. Unable to access the 'Default Web Site' on this computer.

I have checked in Server Manager and IIS is definitely installed. I opened the IIS Manager, and from there I *can* browse to the Default Web site.

For the 1st message, there is a link to http://technet.microsoft.com/en-us/library/aa997645.aspx, but that site doesn't contain any useful information for Exchange 2010. For the 2nd message, there is a link to http://technet.microsoft.com/en-us/library/aa997698.aspx, but I tried that and still get the same error.

Any help is greatly appreciated. Thanks James.

Because MS designs, tests, and supports that very specific configuration. They have no idea how any of us are configuring our DCs. :) It's kind of like OSX and Macs, Apple knows *exactly* what is going on and can build OSX to fit the hardware.

Checking the IIS 6 Management Compatibility in the server manager/web server (iis)/add role services worked for me. No powershell, no scripts, just check a box and retry the install. It would be nice if this was clearly documented as it was
literally the only thing that stopped a vanilla install from moving forward. So simple, put it on the install checklist: IIS 6 Management Compatibility must be set to continue, just like it asked for the Office 2007 filter install, etc.

Open Powershell with elevated rights using "Run As Administrator", and run below cmdlets to install prerequisites... •Import-Module ServerManager •Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy
-Restart •Set-Service NetTcpPortSharing -StartupType Automatic This worked for me too.

I did some investigations and found out that my problem was that the IIS 6.0 Metabase Compatibility
feature was not checked by default when I installed the Web Server Role (IIS). After adding that feature, the Exchange Readiness Check ran with no errors!
